6 Chapter 1 VIDOS-NVR The VIDOS-NVR is a software for digitally recording and replaying video sequences. NVR stands for Network Video Recorder, because the VIDOS-NVR enables any standard PC (commercial server) with sufficient storage capacity to function as a digital network recorder. External storage or RAID systems are also supported. The VIDOS-NVR offers completely new technology for network-based storage of digital video data. In addition, integrated ANR technology (Automatic Network Replenishment) ensures complete restoration of digital data in the event of network failure. The VIDOS-NVR records video, audio and metadata. It is also possible to access each camera connected to the system independently of the computer or the camera location. A VIDOS-NVR application is very flexible and scalable. Any device with a direct interface to the network can be integrated. This makes it possible to register further video sources whenever required, and integration of additional memory is a simple matter. The ANR technology integrated in the VIDOS-NVR protects the system against data loss due to network failure. Network failure is registered immediately. After restoration of the network connection, gaps in the recording are filled in automatically. In this process, the ANR technology inserts the missing parts from the local hard drive recording of each device seamlessly into the gap in the network recording. The VIDOS-NVR is generally operated using VIDOS all-purpose video management software from VCS, but independent direct access using a Web browser is also supported. 6 VIDOS-NVR

7 Chapter 1 Overview of functions The main functions of the VIDOS-NVR are: Device-independent digital recording of video, audio and metadata Faster, more convenient search function to access desired video sequences Availability of the recorded video images on the entire network worldwide Simple integration of an unrestricted number of cameras and storage media Immediate integration in VIDOS Direct access from any location via a Web browser User-friendly graphical operating interface Gap-free storage, even when the network fails, due to ANR technology Supported components The VIDOS-NVR supports data recordings from all VCS hardware products. VIDOS from VCS is supported for replay purposes. VIDOS-NVR 7

A time bar is displayed below the video image for easy orientation. If a recording has already been selected for replay, the time bar shows the associated time interval. A blue bar with a green border represents the time for the selected recording. A yellow scroll thumb indicates the position of the current image in the recording. The position and scale of the time bar can be changed. If the interval displayed is increased, additional recordings may become visible. The following buttons are available for adjusting the time bar: moves the time bar toward the left moves the time bar toward the right reduces the time interval and increases the level of detail 30 VIDOS-NVR

31 Chapter 4 increases the time interval and reduces the level of detail Buttons for controlling the replay are displayed below the time bar. The buttons have the following functions: jump to the beginning of the recording, jump to the previous recording in the list fast rewind stop play pause fast forward jump to the end of the recording, jump to the subsequent recording Note When fast forward or fast rewind are used, the VIDOS-NVR jumps from one I-frame ( intra-frame ) to the next. This can result in a somewhat jerky display. The size of the jumps depends on the GOP ("group of pictures") structure and the GOP length of the video source (find more information in the manual of the respective video server). The replay rate is controlled using the scroll bar to the left of the buttons for replay control. 100% means normal speed. Lower values reduce the replay rate and higher values increase it. Change the time bar as desired. Select the yellow scroll thumb using the mouse and, keeping the mouse button pressed in, drag it to the time position where the replay is to start. Use the buttons and links described to control the replay of a selected recording. Note When the VIDOS-NVR is operated via VIDOS, even more options for replay control are available. VIDOS-NVR 31

32 Chapter 4 MPEG decoder installation If no video image is displayed during replay, it may be necessary to install a current MPEG decoder.
